Should I even acknowledge this person?

Okay so- I am an avid Yelp! user. I decided to write a review on a restaurant that I recently went to. I gave it a decent rating, the only thing I said that could have been perceived as negative was that the prices were a little much for my taste. (for 1 appetizer and about 6 drinks it was $80.00 for me and my friends)

anyway, I thought I was being fair, and nice while giving a good well rounded opinion. A few days later I saw that I had received a message from the owner saying “if you dont like the prices then dont come back, im not changing them”

this caught me off guard, so i told him that he has no customer service skills and I wasnt asking him to change his prices, but since he was being such an a$$ about it I said I would be taking my business elsewhere. Then he responded with the same message. So rude.

I was going back and forth on whether to edit my review so people would know how stupid this owner is and I finally decided to. I didnt owe him anything. At least I am hopefully saving someone money if they see it.

Finally I thought this situation had settled down, but then low and behold i got ANOTHER message from this guy after I edited it saying: I know who you are- we dont need your star or your review”

At this point I am so beyond over dealing with this retard but I am contemplating editing my review again- I mean why the hell is he threatening me?

So my question is, should I edit the review again so potential customers can see how nuts this guy is or just ignore it? How would you say it?
